New Smoke Detectors and the Electrical Circuit List

We have been having the smoke detectors going off for no apparent reason, in the middle of the night. One possibility is that these are the wired-in smoke detectors that were installed when the house was built, in 1986. Smoke detectors, in general, are only supposed to last 10 years; these are now over 25 years old. Probably time to replace them.

I put in two new new Kidde FireX Model PI2010 Dual Sensor Smoke Alarms. Home Depot, $64.89. These provide both an Ionization sensor and a Photoelectric sensor. This replace the earlier ones that were ionization only.

Both the previous smoke alarms and the new ones have a "easy connect" feature that allows the smoke alarm to be plugged and unplugged easily without the need for re-wiring, but, of course, the connectors are incompatible, so I had to first disconnect the old connector and re-wire in the new connector. This requires finding the appropriate electrical circuit for each smoke detector, so I could shut off the power at the circuit breaker box.

The bedroom smoke alarm is on circuit 25; the hallway smoke alarm is on circuit 35.

As long as I was doing this, I created a spread sheet to list each electrical circuit and what I think is on it.

This complements the previous circuit list that I had on two sheets of yellow tablet paper. One problem is how to refer to the rooms; trying to identify the bedrooms by occupant ("Kids, Guest, Lauren's, ...") is problematic since they have moved in, out, and around.
